[jdom-interest] Tagsoup, JDOM, Xpath

Hi JDOMistas!

I am having a problem using the XPather add-on to Firefox with JDOM
and Tagsoup and hope one of you may be able to help me.

I point Firefox at
http://examples.pushtotest.com/responder/htmlresponder?
file=file2.html and use XPather to generate an XPath expression to
point to the Type selection list in the second form. XPather gives me:
/html/body/form/form/p/font/font/table/tbody/tr[6]/td[2]/select

I then try to apply the XPath expression using JDOM and Tagsoup:

builder = new SAXBuilder("org.ccil.cowan.tagsoup.Parser")
doc = builder.build( StringReader( html from http://
examples.pushtotest.com/responder/htmlresponder?file=file2.html ) )
xpathr = JDOMXPath( xpathexpr )
xpathr.addNamespace("h","http://www.w3.org/1999/xhtml")
results = xpathr.selectNodes( doc )

and results returns no nodes.

I found that Tagsoup adds its own default namespace of 'h' with a
value of 'http://www.w3.org/1999/xhtml'. An Xpath expression of '/
h:html/h:body/h:form[2]' returns the second form correctly.

I suspect this is some Tagsoup weirdness.

Anyone have an idea on why the full XPath expression to the select
form element returns no nodes?

-Frank
